Unable to boot

[Elie94]

Hi 

I installed windows 10 but in the last step of installation the laptop was reboot but the laptop couldn't to complete installation (the laptop was work for 4 second till hp logo appear and restart after that ).

I tried to use esc,f1-f12 to enter bios but the laptop didn't respond

I also tried to remove the removable batteries and changing hard drive and ram but nothing changed .

I also installed bios from hp driver center on usb flash to update bios but my laptop didn't respond also.

Please help me .

You've mentioned a lot of things you did -- but we need to know what the state of the laptop is now.

Does it turn on and get to the HP logo? Does it get beyond that to Windows boot and login?  Does it even turn on?
